COMBINED RAILROAD-GATE AND SEMAPHORE.

SPECIFICATION forming part of Letters Patent No. 363,675, dated IVIay 24:, 1887.

Application filed June 17, IFEB. Serial No. 205,431. (No model.)

f0 all whom it may concern-.-

Be it known that I, EDWARD SPENCER PIPER, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, manufacturer,' have invented a Combined Railroad- Gate and Semaphore, of which the following is a specification.

The object of the invention is to design a safety roadgate to work in connection with the semaphore patented by mein the United States on the 14th day of October, 1884, under No. 306,641, and in Canada on the 30th. of April, 1881, under No. 19,269, the arrangement being such that a number of gates and semaphores can be operated simultaneously from one spot; and it consists in the peculiar combinations and the novel construction, arrangement, and adaptation of parts, as more fully hereinafter described and claimed.

Figure 1 is a perspective view showing two roadsor highways crossing a railWaytrack, safety-gates for the highways being connected to the semaphore-posts used as signals for the railway-track. Fig. 2 is a crossseetion of the track, showing the position of semaphore and connections shown'at the left-hand side of Fig. 1. Fig. 3 is a cross-section of semaphorepost A, showing meansof operating the gate.

In the drawings like letters of reference in dicate corresponding parts in each figure.

A is the semaphore-post, near the base of which the safety-gate B is pivoted, the semapl1016lfl1l1p case 0 being placed on the top of the post A and operating in the manner dc; scribed in the patents hereinbefore referred to.

D is a rod connecting the vertically'inovable signal jacket-of thelainp case 0 with the safetygate B.

E is a gear-wheel fastened upon semaphorepost A, and through which the pivoted shaft of the safety-gate B passes. This gear-wheel meshes with the gear-pinion F, fastened to the spindle G, which is journaled upon the gate Band provided with a crank-handle, II. This connection described enables the safety-gate B to beraised or lowered by simply turning the crank-handle H; and as the verticallymovable jacket d of the lamp-case G is connected by the rod D tothe gate B, the said jacket d moves with the gate, and is arranged way'and a white light from the railroad-track, and when the gate is elevated so as to open the highway a white light in the semaphore will be seen from the highway and a red light made visible from the railroad-track. In ad dition to these signals, I provide a lamp, I, which I hang upon the gate D, as indicated. This lamp has only glass upon the two sides which face the highway, so that the said glasses,

which are red, will not be visible to the enwheels K and P in the end of each of the two pivoted shafts or spindles in the gates B shown on the semaphore-posts A to the lefthand side of Fig. 1. For the convenience of operating,Iusuallyplacethesesprocketwheels K and P on the side of the post opposite to that on which the gate B is situated.

Around the sprocket-wheel K, I carry an endless chain, L, up the post A sufliciently high so that it can pass over the highway without interfering with passing teams; and in order to carry it over the said highway I pivot on the post 'A the small sprocket-wheels a and b, carrying the chain L over them, asindicated, to the next semaphoreposawhere it is carried down and around a sproeketwheel, K, attached to the pivoted shaft of the latters gate. In this way, as will be understood by reference to the drawings, all the gates connected in this manner operate simultaneously in the same direction.

In order to operate gates on opposite sides of the railroad-track a wire may be arranged in the same manner; but I think it will be better to'extend a shaft, M, below the track and journal it in the posts A opposite to each other, fixing a sprocket-wheel, N, to each end of the shaft and connecting them by endless chains 0 to the sproeket-wheels P on the pivoted shafts of the gates B.

From this description it will be noticed that any number of semaphores may be operated simultaneously from one point.

What I claim as my invention is- 1. The combination, with the post A, vertieally-1novable jacket d, gate B, pivoted to said post, and the rod D, connecting said gate and jacket, of the gear-wheel E, secured to the post, spindle G, and gear-pinion F, all substantially as and for the purpose specified.

2. The pivoted gate B, connected to the vertieally-movable jacket (Z by the rod D, in combination with the chain 0, sprocket-wheel N, sprocket-Wheel P on the pivot of said gate, and shaft M, arranged to operate simultaneously two or more safetygates, substantially as and upon and moving with the gate B and pro- 20 vided with a handle, and the gear-pinion F on said spindle and meshing with the gearwheel E, substantially as and for the purpose specified.

4. The combination, with the pivoted gate 25 I EDVV. S. PIPER.
